This was a delightful read. Reminded me of my time working on low power FHSS radio gear. We truly take modern wireless technologies for granted!

Not sure if being so opinionated about Rust is a good idea, but very cool nonetheless. Looks well done, excited to tire kick it.

Curious how you see this stacking up against things like Pulumi?

Are you really grand standing against an AI model rn

They are just going where there is money.

I was an early customer of Flexport and got to talk to him on a number of occasions. I felt the same way about him. Total beast.

Your outrage radar is a little too sensitive pal.

In classic HN style, half of the comments have devolved into variations of dEbUgGeR bEtTeR and PrInT bEtTeR...

Newflash! You can do both, and sometimes one is better than the other.

Can you share some examples of high bandwidth 900 radios? In my experience, it’s difficult to get bitrates above ~100kbps on 900 over any meaningful distance.

I tried (and failed) to build a GoTenna competitor using LoRa and what you say here is 100% correct. Large scale mesh networks are incredibly difficult to build and often end up requiring extreme optimizations for specific use cases. We ultimately abandoned mesh networking in favor of a TDMA approach with base stations.

“smart home without the WiFi configuration” is exactly what Amazon’s network is for, but it won’t be anything more than that. The bandwidth and latencies required for content rich applications is simply not there. Sidewalk is cool enough without trying to sell the magic mesh network pipe dream.
